Abstract
1. Process for the preparation of ethyl carboxylates by reacting a mixture containing carbon monoxide and hydrogen with the corresponding methyl carboxylates, in the liquid phase, at a temperature of between 175 and 250¬ C, under a total pressure of between 50 and 600 bars, in the presence of ruthenium and an iodine-containing promoter, the atomic ratio I/Ru being greater than or equal to 5, characterised in that the reaction is carried out in the simultaneous presence of cobalt, the atomic ratio Co/Ru being less than or equal to 1, at least one alkyl iodide and at least one inorganic or organic ionic iodide in which the cation is chosen from the group comprising alkali metal cations, alkaline earth metal cations and quaternary ammonium or phosphonium cations.
